How to select a capacitor bank for power factor correction?
If 4% < THD(u)% ≤ 7% we suggest a heavy duty PFC capacitor bank with suitable harmonic detuned reactors; If THD(u)% > 7% we recommend the installation of an active harmonic filter . Finally, if both THD(I) and THD(U) are measured and do not result in the same type of power factor correction, you must chose the most rigorous solution.

What is the Use of Reactors and Shunt Capacitor Banks?
For this reason these reactors are termed detuning reactors and the capacitor bank as a whole is referred to as a detuned bank. In the figure above, the series reactors have been described as 7 % reactors. This shorthand terminology infers that the reactor reactance is 7 % of the capacitor reactance at the fundamental frequency. The resulting tuned frequency of …
